Improvement in water-wheels



' UNITED STATES PATENT OFFICE.

y IMPROVEMENT INr WATER-WHEELS.

Specication forming part of Letters Patent No. 49, l I4, dated August 1, 1865.

To all 'whom t may concern:

Be it known that I, ANDREW JAMIsoN, of Taylorstown, in the county of Vl/'ashington and State of Pennsylvania, have invented a new and useful Improvement in Overshot Water- Wheels and I (lo hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which` Figure 1 is a side view ot my invention, partly in section 5 Fig. 2, a front or face view of the same.

Similarl letters of reference indicate corresponding parts.

rIhis invention relatesl to a new and useful improvement in overshot waterlwheels; and it consists in constructing the buckets in such a manner that they will receive the force ofthe Water and the wheel be driven by the impact as well as by the gravity of the water.

The main portion of the wheel may be constructed in the usual manner, A `being the shaft,C the arms, D the rims, and E thesole,7 which forms the inner sides of the buckets.

rIhe buckets are constructed in a peculiar manner, so as to have two parts or portions,-

F F', as shown clearly in Fig. 1. The inner parts, F, are of a shape corresponding nearly to that of the ordinary buckets, the front or outer parts, c, having an oblique position, but not extending out to the edges or peirpherie-s of the rims D, as in ordinary wheels. The botcomms b of the buckets extend fully out to the edges of the rims D, and a space or opening, c, is madein them extending their whole length;

a space between them, as shown clearly in Fig. l

1. By this arrangement it will be seenthat the water as it strikes the wheel will expend its force against the bottoms ofthe outer parts orportions, F', of the buckets and pass through the opening cinto the rear or inner parts, F, ofthe buckets underneath, in which it is retained until the buckets reach the lower part of i the wheel underneath the sha-tt A. The wheel, f

therefore, will be driven both by the impact and the gravity ot' the water, whereas the ordinary overshot wheels are driven by the gravity of the wateronly. My improvement, there fore, will add materially to the eieclive power of the wheel.

The improvementmay be applied to old wheels or those in use, and the buckets may be ot'wood or of wrought or cast metal.

I claim as new and desire to secure by Letters Patent- Constructing the buckets of an overshot water-Wheel in two parts, F F', the former, F, being so arranged as to contain or hold the water so that it can act upon the wheel by gravity, while the latter, F', are provided with openings c, and so arranged as to admit of the Water acting upon or against them by impact and then allowing it to pass into the inner parts, F, of the buckets below, substantially as described.
